But seriously, it's not like we even expect OC. I certainly don't. But being dishonest is far worse than the fact that it's not OC. I personally care more about the lulz of the content rather than the person contributing it. But you should always give credit where it's due. At least in the description. If you don't know the source, then it's fine. If you do, have the common decency of putting the artist's name on the content or the description. Removing it is a major dick move.

i literally spent 10 minutes looking for the author to something for someone, i got pissed because everywhere i looked there wasn't a watermark. finally found the original author, hadn't even watermarked it.
